Experimental insights reveal optimal lightweight block ciphers for enhancing security in resource-constrained IoT devices, guiding designers.

The aim is to evaluate and provide design considerations for lightweight symmetric block ciphers in smart IoT applications.
Implemented nine lightweight block ciphers on ARM Cortex-M3-based LPC1768 IoT hardware
Evaluated design metrics including memory utilization, execution time, energy, and power consumption
Compared the performance of each cipher in various IoT contexts
AES block cipher showed the highest evaluation metric values, stressing the necessity for lightweight alternatives
SIMECK, SPECK, SIMON, and SPARX were recommended for health systems needing speed
Ascon and Midori were suggested for energy-efficient transportation systems.

Nazish et al. (2026) studied this question.
